SATURN L200 SMELL PROBLEM

2003 Saturn L200 • 2 miles

The emissions light started blinking. The car started to shake suddenly. Strong burning smell. I don't know of smell was plastic, oil or rubber. Couldn't tell difference. Odometer broken for years, no idea of mileage. Shaking was at low speed. Whole car felt like it was shaking. Now I'm afraid to start it to take to a mechanic. Thanks- mariya
